Enabling highly automated screening solution for latent tuberculosis in all throughput segments

QIAGEN (NYSE: QGEN; Frankfurt Prime Standard: QIA) and DiaSorin (FTSE MIB: DIA) today announced the U.S. launch of an automated workflow for QuantiFERON-TB Plus (QFT-Plus), the fourth-generation modern gold standard for latent tuberculosis (TB) detection, on DiaSorin’s LIAISON platforms.

The U.S. Food and Drug Administration (FDA) approved the LIAISON QuantiFERON-TB Plus Test, developed by QIAGEN and DiaSorin to offer streamlined laboratory automation for latent TB screening, supporting the conversion from tuberculin skin tests to modern blood-based QuantiFERON technology. The highly automated workflow on LIAISON platforms provides QuantiFERON customers a powerful, highly flexible automation option for all throughput ranges.

Embedding QuantiFERON assays in the broad assay menu of DiaSorin’s LIAISON analyzers also gives current LIAISON customers an attractive new assay option with significant growth potential. The workflow pairs QIAGEN’s standard QuantiFERON-TB Gold Plus Blood Collection Tubes (QFT-Plus BCT, containing the core QuantiFERON technology) with DiaSorin’s newly launched LIAISON QuantiFERON-TB Plus detection assay. More than 8,000 LIAISON systems have been placed worldwide, primarily in hospital laboratories.

“We are pleased to announce FDA approval of the LIAISON QuantiFERON-TB Gold Plus Test for use on the LIAISON platform and the broad-based initiation of our launch for this new automation option in the United States. The validation of the QuantiFERON technology with the LIAISON platforms further reinforced the clinical profile of QuantiFERON-TB Gold Plus,” said Thierry Bernard, Interim CEO of QIAGEN and Senior Vice President, Head of the Molecular Diagnostics Business Area. “QFT-Plus users are gaining access to the LIAISON’s powerful, highly flexible automation for all throughput segments, as well as to LIAISON’s broad menu of more than 100 tests. The LIAISON workflow for QFT-Plus was introduced in Europe in 2018 and is planned for China in 2020. Combined with front-end automation options for liquid handling, the LIAISON workflow for QFT-Plus delivers significant gains in turnaround time and efficiency.”

“Today we made a step further in our strategy to drive the conversion to the most advanced solution available in the market for the detection of latent tuberculosis,” Carlo Rosa, Chief Executive Officer of DiaSorin Group, commented. “LIAISON QuantiFERON-TB Gold Plus Test, already available in Europe since September 2018, is now available in the United States on the LIAISON family platforms and we believe this solution for laboratories will furtherly strengthen our positioning as a specialty player”.

QIAGEN and DiaSorin initiated a collaboration in 2017 to develop new tests for the LIAISON family of analyzers based on QIAGEN assay technologies. Additional tests based on QuantiFERON technology, which provides a unique, efficient way to detect asymptomatic infections and other risks that may not be detected with standard diagnostic technologies, are planned for adaptation to the LIAISON platforms.

In addition to the DiaSorin collaboration, QIAGEN is partnering with two leaders in liquid handling solutions to provide options for automated pre-analytical processing for customers who implement the single-tube collection process for QFT-Plus. These collaborations enable customers to use the Hamilton Robotics Microlab® STAR™ automated liquid handling workstation or the Tecan Fluent® Laboratory Automation workstation to automate the manual step of aliquoting samples from a single collection device (such as a standard lithium heparin blood collection tube) into QuantiFERON-TB Gold Plus tubes for analysis.

QuantiFERON-TB Gold Plus is registered in more than 75 countries in North America, Europe, Asia, Africa and Latin America. QIAGEN’s QuantiFERON-TB Gold (QFT) and QFT-Plus tests are the market-leading blood tests for latent TB, with faster, less labor-intensive and more accurate insights than the century-old tuberculin skin test. QFT-Plus also has the future potential to deliver increased clinical utility by adding measurement of CD8+ T-cell immune response to detection of CD4+ response. CD8+ T-cells have been shown to play an important role in the development of active TB, and QFT-Plus has been cited by international agencies for its potential benefit among migrants and other populations.

Tuberculosis is a contagious bacterial infection spread primarily through coughing by patients with the active pulmonary form of the disease. In 2016, there were 10.4 million new cases of active TB worldwide and 1.7 million deaths from TB, according to WHO estimates. In latent tuberculosis infection, the bacterium infects a person but produces no symptoms unless it progresses to active disease, at which stage the patient is highly contagious. As part of comprehensive programs to eradicate TB, WHO and other international organizations have expanded their guidelines for screening high-risk individuals and treating those with latent infection to help prevent further contagion and reduce the disease burden.
